DAVID W. BOVEE, OF WVATERLOO, IOWA.

SPECIFICATION forming part of Letters Patent No. 788,391, dated April 25, 1905.

Application filed September 28,1904. Serial No. 226,369. I

To all whom it may concern.-

Be it known that I, DAVID W. BOVEE, a citizen of the United States, residing at Waterloo,

in the county of Blackhawk and State of Iowa, have invented certain new and useful Improvements in Apparatus for the Construction of Plastic Walls, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in an apparatus for the construction of plastic or cement walls.

The object of my invention is to provide an apparatus of this character in which the outer face of the wall is formed to appear as stone and said outer face being made of a liner grade of material, while the backing is made of coarser material, thus lessening the cost and at the same time forming a fine-appearing wall, which is more durable and adapted to stand the weather to which it is exposed,

I the outer and inner faces of coarser and finer material being so interlocked that there is no possibility of the same separating and falling from the main backing of coarser material.

Another object of my invention is to provide detachable sections forming the different blocks of imitation of stone and providing the same with securing means whereby they may be secured together and insure of a vertical or oblique alinement, as desired.

A still further object of my invention is to provide means for forming said walls with vertically arranged fines or hollow spaces therein, thus reducing the cost of the same and at the same time providing means for circulation of air therethrough.

In the accompanying drawings, Figure 1 is a perspective view of a section of a wall, showing the general appearance of the same when completed. Fig. 2 is a transverse vertical sectional view of the wall during the construction thereof, showing a number of mold-sections in place. Fig. 3 is an enlarged front elevation of the mold-sections. Fig. 4 is an enlarged transverse vertical sectional view of two of the removable mold-sections, showing the means for locking the same together. Fig. 5 is an enlarged perspective View looking toward the front, showing the vertically-movable divisional plate and means for supporting the same. Fig. 6 is a perspective view of the supporting-shelf from which the mold-sections are built upwardly during the construction of the same. Fig. 7 is a top plan view of the collapsible member for forming the vertical hollow portions in the wall. Fig. 8 is a side elevation of Fig. 7. Fig. 9 is a side elevation of Fig. 7, showing the same in its collapsible position so that the same may be moved upwardly. Fig. 10 is a side view of a mold-sectioi1,showing the outwardlyextending members at an angle for the purpose of building walls with angles therein.

Referring now to the drawings, A represents a backing or wall formed, as shown, of

planking, and, as shown, it preferably started from the ground and is built upward as the wall progresses in its construction, this backing forming the rear face of the wall and also forming a point or support from which to work during the structure of the wall. In starting a wall of this character, as before stated, the backing A is first run up a sufficient height, and a cement or other plastic material is formed in front thereon, and the L- shaped plate B is secured thereto by means of a bolt I), which passes through the wall and through the backing, thus forming a starting or supporting point for the front mold-sections C to start. It will be seen that the portion'B of the L-shaped plate Bforms aledge upon which the sections C of the mold rest and are supported. These plates are placed a distance apart to form a support across the entire front of the wall or that portion being constructed. The mold-sections C, as shown, are of an oblong form, and the inner faces are provided with concaved roughened faces 0, which form an imitation of stone, and surrounding said concaved faces are smooth ledges 0, which form a finished smooth edge around the concaved roughened portion, and thus the Wall when completed has the appearance of cut blocks of stone or blocks of cement stone laid in the usual manner. Said front mold-sections are provided on their outer faces with outwardly-extending arms D, which, as shown, are provided with vertically-arranged screw-openings d, which are adapted to receive the screws D, which pass therethrough and are adapted to engage the outwardly-extending arm D, carried by the upper end of the section below. The said arms are so arranged upon the sections that when the sections are together, as shown in Fig. 1, the arms of one section are in an alinement with arms carried by the section below, and the screws rest upon said arm. By this arrangement it will be seen that the sections may be adjusted by the turning of the screws, so that they are in perfect alinement and are arranged in a vertical position. Surrounding the wedge-shaped arms is a link or ring E, which is adapted to be driven thereon after the proper adjustment, and thus the two sections are held in said positions. The said front sections, as shown in Figs. 1 and 3, are provided at their edges with recesses or cutaway portions F, through which passes the rod-supporting members G, which, as shown, are provided with an elongated slot g and a movable stop G, which is provided with a set-screw g, which passes through the slot 9 and by means of which said stop is moved upon the member G, and the same is allowed to pass farther inward, and thus the thickness of the veneer or coating of finer outer material may be regulated and at all times bekept the same thickness, as hereinafter more fully described. The inner ends of the said members are provided with vertically arranged openings .r and passing through said openings are rods H, which have their upper ends provided with eyes or rings It, which prevent the same from passing down through said openings. Secured to said rods H is a divisional plate I, which, as shown, is provided with ears 6, through which the rods H pass, and the upper set of ears are provided with set-screws i, by means of which the divisional plate is looked upon the rods and by means of which the plate is vertically raised on the rods as the cement or composition is filled in on each side thereof. The said plate, as shown, is corrugated or fluted, which forms a greater holding or interlocking surface, as hereinafter described.

In order to make the completed wall hollow or provided with vertically-disposed hollow fines or passages, I provide a collapsible cylindrical member J, which is placed between the divisional plate I and the backing of wood A, and the coarse cement or plastic material is placed around the same, while the finer or better material is filled in between the divisional plate and the front sections. When the material is nearly up to the top of the divisional plate, the same is released by turning the thumb-screws i, and the divisional plate is raised so that the lower end is just within the plastic material, thus bringing the coarser and finer material in contact with each other. The material is then firmly compressed together by any means, but preferably in a manner which causes the fluted or corrugated surfaces of the two materials to firmly adhere together and to be formed as a single wall, with the outer liner veneered face forming an outer stone-appearing face. After the same has been firmly compressed the collapsible cylindrical member is collapsed and elevated until the upper end is near the top of the plastic material and the operation of filling in and compressing is repeated. After the vertical divisional plate has reached the upper end of the rod the set-screws carried thereby are released and the rods H are withdrawn from the members G and said members are Withdrawn from the plates I and inserted at a different point above through the openings, and thus the wall is gradually built step by step, yet an unbroken Wall is formed.

The collapsible cylindrical members J are formed of two semicircular plates or members J and J which are pivoted at 7', and pivotally connected to the upper end of said sections J and J at 1' and j are links K and K, which are pivoted together at is, and thus by pulling up upon the links at the center the upper ends of the two sections are drawn together, thus reducing the size of the said member, so that it may be readily moved upward. The link K is provided with an extended end which serves as a stop to prevent the links from being pushed too far up. The link is provided with an extended end 70 which serves as a stop to prevent the link from being pushed too far down, but allowing the same to be forced down far enough to pass the center of said pivotal connection, and thus serving as a lock after it has passed the center to prevent the sections from being pushed together by pressure on the outside thereof. The lower ends of said sections J and J of the cylindrical member is provided with spring members 0 and O, which are pivoted thereto and have their outer ends eX- tending outwardly beyond the said sections, and thus the spring members are normally outwardly spring-pressed, and thus when the said cylindrical member isdrawn upward the spring members are forced inwardly; but when the same reach the upper edge of the cement the spring members are forced outward and rest upon the upper edge of the ocment, and thus the cylindrical member is prevented from sliding back within the opening formed therein.

As the wall is continued upward the backing is built up, and as the cement or plastic material of which it is built hardens the front blocks from below are removed and placed above, and thus the wall is continued upward indefinitely, and a great number of mold-sections are not necessary, as the material will harden in a short while sufficient to remove the molds.

In Fig. 3 I show the mold-sections C with the overlapping lugs L and L, which are adapted to overlap each other and interlock, which insures an exact alinement of the inside edges of the mold-sections. The mold-sections, as shown in Fig. 10, have the outwardly-extending arms D extending at an angle, which allows of the mold-sections being placed at an angle for building around corners and the like.
